Wetmore Roller Mill | Lockwood Ag

The Single Mill has one hopper feeding the rollers. The double mill has two hoppers combining two roller mills with one power source, driving two pairs of rollers and the discharge auger. This enables the economical milling of different grain combinations which are then mixed in the base hopper and conveyed by the discharge auger.
